' Application mea June a,

for the easy opening and closing of thev valve, which object -is accomplished bythe mechanism shown in the drawings, in which: Figure 1 is a view of the exterior of a valve case 'with the improved mechanism .attached thereto; Fig. 2 is a section on the line 2- -2, Fig. 1, and Fig. 3 is av section on the line 3 3, Fig. 1. Y

Tithin the case 1 is disposed the valve 2 operatively controlled by the spindle 3 eX- tending through the wall of the case to the exterior thereof, all in a well known manner, which need not be more particularly described. l.

To the outer end of spindle 3 is operatively attached the inner venol of the levervv 4, to

the outer end of which lever is pivoted aty 5 one end of the screw 6, which extends through and interiorly engages the correspondingly 'threadedbushing 7, which interiorly androtatably engages the hub 8, which is disposed on said bushing and furnished with stem 9, which is rotatably disjposed in the case 1, being confined lengthwise therein by nut 13, thus enabling hub 8 and therewith bushing 7 and screw 6 to oscillate, as the screw moves lengthwise through the bushing, as necessitated by the pivoted connection of the screw with the lever 4.

The bushing 7 is furnished centrally, exte'riorly, with the collar 7a and is threaded at its upper end 7b for engaement by the nut 10, between which collar ga and nut 10 is confined the hub 8, which arrangement OF BOSTON, MASSACHUSETTS, A CORPORATION VALVE.

prevents lengthwise movementl of the bushing 7 while permitting it to be `'freely rotated istante] by lthe wheel 1l mounted on the lower endlr thereof. The range of movement of lever v4 is limited by stops 14 disposed on the case... f `Iclaim: Y

1. Inl a valveof the character described, means for operating the valve controlling spindle comprising, in combination, alever operatively attached to the spindle; a screw' having oneend pivoted to the lever; a bushmg rotatably disposed on the screw in threaded engagement therewith; a hub swivelled in the case about an axis at right an# gles to the longitudinal raxis of the screw and interiorly rotatably engaged by the bushing; and means for rotating the .bushing and ,i

thereby actuating the screw. y

2. A valve having, in combination, a valve gate, a spindle on which the-gate is mounted to permit swinging thereof, an oscillating lever attached to the spindle, an actuator ymember pivoted atthe end of the oscillatmg lever, a bushing through which thek actuator member is capable of longitudinalV movement, means for mounting the bushing to permit rotative movement thereofL about an'axis at right angles to the longimeans for moving the actuator member longitudinally through the bushing.
